SCREEN.

Specication of Letters Patent.

- Application led March 7, 1912. Serial No. 682,223.

To all 'whom it may concern: 'y

Be it known that I, RICHARD DENNIS STACRY, a subject of the King of Great Britain and Ireland, and a resident of Lau-V rance street, in the post.town of Maldon, in the county of Talbot, Stateof Victoria, Commonwealth of Australia, have invented certain new and useful Improvements in Screens, of which the followmg is a specification.

This invention relates to screens of theA character consisting of a series of laths adapted to be drawn into a restricted area and also capable, when extended, of being opened a art to Vadmit light or ventilation. The obJect of the invention is to provide a simple screen which will be fire proof and weather resisting.A In addition by the screen ventilation may take place with safety and without unnecessary movement or rattling.

The screen may be used for window purposes or as a fire guard to prevent burning embers falling out of a domestic grate.

It may also be used to assist the draft in starting a iire. i

It may, further, beused as an advertising screen and for a'variety of other purposes, not being cumbersome or unsightly.

Referring to the drawings which form a part of. thls speciication:-Figure 1 is an isometric view of ortion of a screen to show the relationship. etween laths thereof. A lower lath is open acting -as a ventilator. Fig. 2 is aV front view of this invention, on a reduced scale, portion being broken away for convenience of illustration. Fig. 3 is an enlarged detail view of two inter-engag ing hinge rolls. Fig. 4 is an end sectional view on a reduced scale, the screen being shown as partly elevated to illustrate the movement of the laths during the elevating operation. It is obvious that an elevating line anda lower lath inclining-line have been delineated in unnaturalpositions for convenience of illustration. Pulleys,.a nd holes adjoining them have also been positioned for illustrative purposes only and need not occupy the positions, shown. Fig. 5 is an end sectional view, on a reduced scale, the screen being fully extended. Lower laths are open to admit light or ventilation. It is obvious that an elevating line and a a framework consisting o -upper lath and near the center lower lath inclining line have been delineated in vunnatural positions for convenience of illustration. Pulleys and holes adjoining them have also been positioned for illustrative purposes only and need not oecupy the positions shown.

The invention includes Figs. 2,- 4 Aand 5) a top member 2 to which are attached Vsuitable hinges 3. Be-

low the top member 2 is a bottom member 4 and extending betweenthe'top and bottom members are side members 5. From the side members may protrude studs 6. Secured to each side member 5 is an outer guide member 7 and an inner guide member 8. The framework may consist of any suitable material or materials and vary in conformation according to the circumstances. surrounding its use.

' Formed in the top member and near the center of thesame is an elevating line hole 9. Adjoining the hole 9 is an elevating line inner pulley 10. Near one'end of the top member 2 is an elevating line -outer pulley 11. Formed in the top member 2 is also a lower lath inclining line hole 12. Adjoining the hole 12 is a lower lath inclining line inner' pulley 13. Near one end of the top member 2 is secured a lower-lath inclining line'outer pulley 14.

Within the framework is a screen consist-- ing of a series of members.. Each member includes an upper lath having two longitudinal edge portions 15 and 16 thereto. .The screen is retained within the framework by means of the hinges 3 which are attached to the edge portion 15 of the extreme upper lath ofthe said screen. Formed in each of the same is' an elevating line slot 17. Each screen member also includes a lower lath having two longitudinal edge4 portions v18 and 19 thereto. the center of the same is an elevating line slot 20.v Formed in each. lower lath near the edge portion 19 thereof is a lower lath inclining line hole 21.

The upper lath of each screen member is;`

provided'along its edge portion 16 with a" hinge roll 22. The lower lath of each screen member is rovided along its edge portion 18 with a hlnge roll 23. The hinge rolls 22 Formed in each lower lath near.

and 23 interengage as shown in lig. 3. Any

' lath as shown.

With the foregoing is used an elevating line havin an inner end 26 and an outer end 2'?. 'll e inner end 26 is secured to the extreme lower lath of the screen. The line is passed upwardly through the elevating line slots, over the inner pulley 1Q and outer pulley l1, as shown. With the foregoingis also used a lower lath inclining line having an inner end 23 and an outer end 29. Upon the line are stops 30. 'lhe inner end 28 of the lower lath inclining line is secured to one of the lower laths of the screen and passed upwardly through the'lower lath inclining line holes 21, over the pulleys 13 and 1li. The inner end 28 may be attached to the extreme lower lath of the screen. @r it may be secured to the lower lath above it as shown. f

With this invention, to elevate or lower the screen it is only necessary to operate the elevating line. Clhe action of elevation is shown in Fig. 4. When the screen is eX- tended and it is desired `to open the lower laths the inclining line is pulled. This moves the lower laths from a vertical toward a horizontal position. rlhe lowest of the lower laths may be operated by the elevating line if desired as will be clear from the drawings. When operating the lower laths by the lower lath inclining line the stops 30 it will be seen, in turn engage with their corresponding lower laths. Ventilation or light is thus admitted through the screen.

lt will be plain that instead of two central lines being used to operate the screen, lines could be used at each side thereof and be connected. Any suitable guide rods or the like may also be used in conjunction with the laths.

Having now described my invention, what l claim as new and desire to secure by Letters katent is z-f l. A screen consisting of a series of lathe hinged together in pairs, an upper lath and a`lower lath forming each pair, and means for laterally inclining the lower laths without interfering with the upper lathe.
